Trajectory prediction for drifting ship allision probability calculations: A trajectory prediction-based method for probability calculations to improve our understanding of drifting ship allision risks in the Dutch North Sea region

The expansion of offshore wind farms in the North Sea has raised serious concerns about maritime safety, in particular the increased risk of collisions—or 'allisions'—where a ship adrift hits a stationary structure, such as a wind turbine. For Rijkswaterstaat, the executive agency of the Ministry of Infrastructure and Water Management, managing...

Going with the Flow: A study on the impact of stratified North Sea coastal currents on energy consumption in dredging projects

The goal of achieving net-zero emissions by 2050 requires innovative ways to reduce energy consumption in all sectors. This thesis presents an in-depth analysis on the effect of coastal currents on energy consumption of sailing dredging vessels and the potential to make use of these currents to minimize energy consumption in dredging projects....

Influence of Charging Infrastructure on the Daily Energy Use of Vessels with a Variable Operational Profile

In the global energy transition where the shift from fossil fuels to renewable energy is needed, wind energy is a growing industry. In the offshore wind industry, Service Operation Vessels (SOVs) are needed to operate and maintain wind farms. To reduce the environmental footprint of SOVs at offshore wind farms, the possibility of battery...

Estimate vessel emissions in ports using AIS data: A study to identify emission distribution patterns in ports and evaluate emission reduction strategies

The shipping industry is responsible for almost 3% of the world's greenhouse gas emissions and is looking for possibilities to reduce their share. The demand for lowering the emissions of the maritime industry creates the need for insight in the emissions. Currently a generic method to specify emissions in space and time, as a function of vessel...

Photovoltaic potential of the Dutch shipping fleet: Experimentally validated method based on photovoltaic power calculations to simulate the energy yield of general cargo inland vessels

Implementing renewable energy generation and more sustainable consumption behaviour in the future inland shipping industry is necessary. Electrification of the inland shipping fleet leads to an increase in electrical energy demand on the consumption side. The generation of decentralized photovoltaic (PV) energy systems on board of general cargo...

A study on the possibilities of using a coupled or schematized numerical method to determine the flow pattern downstream of a discharge sluice: An Ostend case study

In the port of Ostend a discharge sluice is going to be constructed as part of an enforced dike ring. The proposed location of this discharge sluice is close to an already existing marina, the Royal Yachtclub Oostende (RYCO), and hindrance is expected regarding the outflow of the sluice in marina direction. When designing the sluice, an optimal...

An experimental and numerical investigation of the hydrodynamics of the ducted system of a "Van Rompay Turbine": with the goal to capture energy from the current of an ocean, river, estuary or similar

Hydrokinetic energy is an environmentally friendly source of electricity and it has the advantage to be more predictable compared to other renewables. According to IRENA (2020), the capacity of converting hydrokinetic energy into electricity is expected to increase in the coming decades as many concepts are in the pipeline. One of these...

Mapping port operability indicators across the world: Screening the suitability of port locations related to metocean conditions

LOSCO A Ship Lock Scheduling Model

A ship lock scheduling model called LOSCO was developed in order to decrease passage times at locks with two parallel chambers. Three locks were chosen to model, as they are some of the busiest locks of the Netherlands. The Krammersluizen, the Sluizen Hansweert and the Kreekraksluizen. Passage times are not collected at the locks, therefore the...

Estimating Navigable Areas in Scarce data River Environments: A Chindwin Case Study

The seasonal Chindwin river (Myanmar) forms the central artery for transportation in the region. However, the dynamic river behaviour, archaic boat equipment and limited monitoring, yearly results in large numbers of grounding ships, causing injuries and economic losses. A pilot project involving CoVadem technology was initiated in the beginning...

Parametric design-tool to optimize preliminary design of navigation lock chambers

Summary<br/>In the twentieth century a substantial number of navigation locks were build in the Netherlands. The navigation locks built in that era mostly had a life span of 80 to 100 years. This means that in the coming years most of these locks will be in need of either renovation or replacement. Rijkswaterstaat, the administrator of most of...
